Keep a Look out For New
Invasive Plants in the Midwest Flyer
Glenn Nice, Weed Diagnostician, Dept. of Botany &
Plant Pathology, Purdue University
Continuing to get the word out about invasive
plants, a new flyer has been developed by the Midwest Invasive
Plant Network (MIPN) highlighting some of the plants to keep
an eye out for in the Midwest. If you should happen to
come across any of these plants, please contact the Plant and
Pest Diagnostic Lab at Purdue University, for there is a need
to get a better understanding of distribution of these plants.
The full flyer with color pictures and written descriptions
can be downloaded from the MIPN
web site (or directly from
